5-11-2 AC Controller
5-11-2-1 General Description of the AC Controller The AC Controller’s main task is to supply the va rious internal subsystems with AC power and to 
galvanically isolate the scanner from  the on-site Mains Power System. 
An inrush current limiter reduce the peek input current  when the unit is switched on. An EMI filter helps 
to reduce EMI to acceptable...

5-11-2-2 The AC Transformer The AC Transformer is the galvanic barrier between the rest of the scanner and the on-site AC Mains.
Input voltage to the transformer can be either 2 30 VAC or 115 VAC. The transformer has two 115 VAC 
primary windings which are series- or parallel coupled depending on input voltage (see  Figure 5-83). 
Each of the primary windings has  one thermal protection...
